Alexandra began to lose consciousness as an ambulance was moving her from Sandringham Hospital to the Royal Children’s Hospital.

At the RCH, scans showed her skull was fractured in two places, but remarkably there was no damage to her brain.

In intensive care the next day doctors discovered Alexandra’s carotid artery had been dangerously damaged in the accident.

The major artery, which supplies blood to her brain, was blocked, putting her at high risk of a stroke, Ms Weeks said.

Doctors had to give her the right amount of blood-thinners to reduce her risk of having a stroke, but not enough to trigger bleeding in her brain.

Her parents know how lucky she was, not only to survive the accident, but to escape without permanent brain damage.

“I can’t quite believe she’s with us. I feel like we won Tattslotto in a weird way on that day, that we’re not planning a funeral,” Ms Weeks said. “She’s a very sweet, loving little girl, but quite feisty … we call her the destroyer because she leaves this trail of destruction … and she’s got through it partly because she’s a tough little one.”
